The alveolar macrophage plays a number of important roles in the pathogenesis of silicosis and coal workers' pneumoconiosis (CWP). These roles include phagocytosis of dust particles, release of fibrogenic cytokines, and recruitment and activation of

We evaluated associations between dust exposure, demographic factors, and lung function by longitudinal and cross-sectional analyses in 475 steelworkers who participated in at least three spirometry tests over 5 yr between 1982 and 1991. Baseline and

Serum angiotensin-converting enzyme activity (SACE) and lysozyme activity were measured in a group of 40 underground coal miners and two control groups, 20 subjects with sarcoidosis and 15 normal non-dust-exposed volunteers. The miners were grouped f

This study describes the quantitative relationships between early pulmonary responses and the estimated lung-burden or cumulative exposure of respirable-quartz or coal mine dust. Data from a previous bronchoalveolar lavage (BAL) study in coal miners

Pneumoconioses are characterized as irreversible, progressive respiratory diseases. No effective therapy exists to prevent progression of these diseases. Whole-lung lavage (WLL) might limit the rate of disease progression through the removal of dust,

It has recently been suggested that the inhalation of coal in the absence of complicated coal workers9 pneumoconiosis (CWP) or smoking can lead to disabling airways obstruction. The cause of such obstruction has been variously attributed to emphysema

In the 1950s, asthma was defined in terms of reversible airflow obstruction; and then during the 1980s, the emphasis on the diagnosis and treatment of asthma centered on airway hyperreactivity. Recent advances in molecular biology and immunopathology

CWP is a disease distinct and separate from silicosis. Simple CWP is clearly related to the amount of dust deposited within the lungs. Complicated CWP (PMF) results from dust deposition plus other factors. Immunologic and local cellular factors may c

Bilateral sensorineural hearing loss developed in a 64-year-old woman treated with intravenous erythromycin lactobionate for bacteremic pneumococcal pneumonia. Discontinuance of the antibiotic led to prompt correction of the hearing deficit. Reversib

Lung volumes and ventilatory capacity of 9,076 coal miners were determined during the period 1969-1971. The data collected indicate that, while coal mining may in certain instances lead to very minor reductions of ventilatory capacity, such reduction
